ABSTRACT

A shoe or slipper of the turnshoe-type, that is, a shoe which is manufactured by stitching together the outsole and upper inside out, and then turning the construction so formed right side out. The shoe is provided after being turned right side out with a heel, to the front side of which portions of the insole and outsole are secured. The upper incorporates a heel covering portion which, together with an end of the outsole, is retained within a cavity in the heel underside by means of a heel lift.

//EKBR7 64066 Ava/@145 Y5 SHOES BACKGROUND This invention relates to a shoe, particularly a slipper, of the type known in the art as a turnshoe in which the outsole and upper are stitched together to form an inside-out construction which must be turned right side out during a subsequent manufacturing step.

Shoes and particularly slippers of this kind which have block heels fixed in position are already known and are popular with the wearers. The heels are nailed on during the production stage, the nails passing through a shank, the insole and outsole, the latter having been taken over the heel and stitched to the material of the upper. In shoes of this kind, because of the method of construction employed in which the outsole (also known as the cosy-outsole) while inside out is taken over the heel and stitched to the upper, the heels are generally mounted inaccurately and inaesthetically, even though the assembly operation is lengthy and tedious.

SUMMARY In the shoe to which the invention relates, this drawback is avoided by the fact that the outsole stitched over the entire length to the material of the upper is taken down together with the insole along the front side of the heel and affixed to the lower side of the latter, while the heel covering, forming one unit with the remaining material of the upper, is likewise affixed to the lower side of the heel.

This design can be adopted with closed, partially backless and also with backless footwear.

DESCRIPTION OF DRAWINGS FIGS. la-h show the individual components forming a closed shoe, before assembly;

FIGS. 2a-d are longitudinal sections through a finished shoe or parts thereof, shown at various production stages;

FIGS. 3a-e show various components, without heel and joint. for the production of another type of shoe in accordance with the invention;

FIGS. 441-11 show longitudinal sections, in accordance with FIG. 2, through a shoe made up of the parts shown in FIG. 3;

FIGS. 5ad show individual components, without heel and joint, for a further version of a shoe in accordance with the invention; and

FIGS. 6a-d show longitudinal sections through a shoe, or parts thereof, made up of the components illustratedin FIG. 5.

DESCRIPTION OF PREFERRED EMBODIMENTS Firstly, with regard to the embodiment of FIGS. 1 and 2, as shown in FIG. 1, the shoe components consist of an upper I, the material for covering the heel being integral with the material of said upper, and also of an outsole 2, an insole 3, a topsole 4, a stiffener 5, a heel 6 with heel lift 7 and a shank 8. The production of a turnshoe from these components will now be described.

First of all, the upper l is stitched together at the heel end and the seams rubbed down. The outer edges of the stiffener 5 are then skived and the inner facing edges stitched together at an obtuse angle. The stiffener 5 is then stitched, along the outer edges, to the upper l, in such a way that the line of stitching of the inner edges align with the rubbed down seam. With the assembly inside out, the outsole 2 is then stitched to the upper I, over a width of 1 mm.

Independently of these operations, the shank 8 is fixed, as by nailing, to the heel 6 (FIG. 2b). An adhesive is sprayed or otherwise applied onto parts 1, 5 and 2, already stitched together, and the insole 3 is inserted, at a distance of 1 mm. from the stitching, between the outsole 2 and the upper 1. The assembly of outsole, insole and upper is then turned inside out and the heel 6 coated at the side and at the bottom with glue, together with the shank 8, is forced into the turned upper l, which has been provided with the soles 2 and 3 and with the stiffener 5.

The rest of the upper material 1 and of the outsole 2, which has been drawn down, together with the insole, over the front side of the heel, is now lasted into a cavity 6' provided in the lower side of the heel 6, and the heel lift 7 is nailed into the heel 6. Finally, the sock 4 is inserted. FIG. 2d shows a longitudinal section through the finished show, which, due to this construction, has the particularly popular characteristics of the so-called cosy shoe, without any expensive production processes, and the connection between the heel and the upper presents a harmonious appearance. Owing to the fact that the outsole and insole are drawn downwards over the front side of the heel it has been possible for the heel covering to form one single unit with the remaining material of the upper. The heel covering may be integral with the upper material, but is can also form a separate item combined with the latter in due course (by the use of an adhesive, by stitching or other known joining operations).

FIGS. 3 and 4 illustrate a shoe built up in the same manner as in FIGS. 1 and 2 (from upper l, outsole 2', insole 3' and sock 4', and also a vamp 5' stitched onto the upper material 1 except that in this case it is partially backless, i.e., has only one heel strap at the back. The construction is nevertheless the same as before, as regards the sole 2', 3, 4, and the heel 6.

A further version of a shoe in accordance with the invention is shown in FIGS. 5 and 6. This shoe likewise is constructed in the same manner as that shown in FIGS. 1 and 2 (from UPP r 1", outsole 2", insole 3" and sock 4", with heel 6 and shank 8), but is backless, the upper material and heel-covering material extending beyond the heel 6, in an upward and in a downward direction, being lasted onto and into the heel respectively.

Obviously, therefore, modifications which will be apparent to those skilled in the art may be made within the spirit and scope of the invention.

What is claimed is:

l. A shoe of the turnshoe type, comprising an upper, an outsole, an insole, and a heel having front and lower sides which lower sides being covered with upper material, said outsole being stitched over its entire length to the upper and, together with said insole, being drawn down over the front side of the heel, said outsole being fixed at the bottom side of the heel together with the upper material covering the heel whereby the upper is connected with the outsole by said stitching and the free edges of the interconnected shoe portions are located in the interior of the shoe, said heel covering forming one piece together with the side portions and front part of the upper, and said heel covering being connected to the outsole in a region of the front side of said heel.

2. A shoe in accordance with claim 1, wherein the heel is formed with a cavity in its lower side and the end of the outsole is lasted into the cavity, and wherein a heel lift is provided to retain said end in place.
